This is only a cosmetic issue. At certain points during installation a
scrollbar is placed at the bottom of the screen. The scrollbar has no function
(does nothing).
To reproduce the problem download and install Crayon Physics demo version. You
can see the scrollbar on the 5th page of the installer (where you have the
option to install a desktop shortcut) as well as on the final screen when
installation is finished.

A regression due to

c4a28490f304167d2257d2de6315f09d577742f2 is the first bad commit
